Campral (Acamprosate) – Patient Information (Australia)

Campral contains the active ingredient acamprosate. It is used to help people maintain abstinence after stopping alcohol, particularly when alcohol dependence is present. This guide explains how Campral works, how it’s usually taken, key safety considerations, and practical tips to support recovery.

Note: Medicines affect people differently. Always follow the dosing advice provided by your healthcare professional and the information on the product label. If you’re unsure about anything in this page, speak with a pharmacist or doctor.

Key product facts

How Campral works (mechanism of action)

Campral is designed to help reduce the likelihood of relapse by supporting the brain’s chemical balance after alcohol has been stopped.

Alcohol dependence alters signalling in the brain, particularly pathways involving GABA (gamma-aminobutyric acid) and glutamate. When alcohol use stops, those systems may remain out of balance, which can contribute to cravings, anxiety, sleep problems, and heightened sensitivity to relapse triggers.

Acamprosate helps restore balance by:

• Modulating glutamatergic and GABAergic transmission associated with alcohol withdrawal and long-term neuroadaptation.
• Supporting a more stable inhibitory/excitatory balance that may reduce relapse risk.
• Working to maintain abstinence rather than “treating” intoxication.

In practical terms, Campral is most helpful when a person has already stopped drinking and is trying to remain abstinent while cravings and withdrawal-related symptoms settle.

Pharmacokinetics: how the body processes it

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated.

• Absorption: After taking tablets by mouth, acamprosate is absorbed into the bloodstream.
• Distribution: It distributes through the body, reaching the central nervous system to exert its effects.
• Metabolism: Acamprosate is not extensively metabolised in the liver (this can be helpful when liver function is impaired, but kidney function remains important).
• Elimination: It is largely eliminated via the kidneys (urine).
• Half-life: The elimination half-life is often described as several hours, supporting dosing multiple times per day.

Clinical implication: Because elimination is mainly renal, dosing and safety considerations are strongly influenced by kidney function.

What Campral is used for

Campral is indicated to help people who are abstinent from alcohol maintain that abstinence in the context of alcohol dependence.

Typical uses may include:

• Supporting relapse prevention for people who have stopped drinking and are in an ongoing recovery plan.
• Adjunctive support alongside counselling, behavioural strategies, and support services.

Important: Campral is not a treatment for acute alcohol withdrawal and it does not “block” the effects of alcohol if you drink.

When to start and timing of doses

Campral works best when taken as part of an organised recovery approach.

Typical approach:

• Start after stopping alcohol and aiming for abstinence.
• Take doses consistently at the times your prescriber or pharmacist has advised.
• Continue for the period recommended for relapse prevention, which may be several months depending on individual circumstances.

Timing tips:

• Try to space doses evenly across the day.
• Use reminders (mobile alarms or a pill organiser) to maintain regular dosing.
• If you miss a dose, follow the instructions on your medication information. In general, don’t double up to catch up.

Can you take Campral with food?

Food effects with acamprosate are generally limited. Many people can take Campral with or without meals, which can make it easier to fit into daily routines.

Practical guidance:

• Choose the routine you find easiest to maintain.
• If stomach upset occurs, consider taking it after food.
• Do not rely on food to “counteract” alcohol. Campral is intended for abstinence support.

Alcohol interactions

The goal of Campral therapy is abstinence. You should generally avoid alcohol while taking it.

What happens if you drink alcohol while on Campral?

• Campral does not function as an “antidote” or deterrent.
• Drinking can undermine relapse prevention efforts and may worsen wellbeing, sleep, mood stability, and adherence to recovery plans.
• If you drink and experience side effects (for example dizziness or nausea), stop drinking and seek advice promptly.

If you are struggling to remain abstinent, it’s important to seek support early—your healthcare team can adjust the plan and add additional relapse-prevention strategies.

Interactions with other medicines

Drug interactions depend on the specific medicines you take and your health conditions. This section covers important general points.

General considerations

• Kidney function matters: since acamprosate is cleared by the kidneys, medicines that affect kidney function or require renal adjustment may be relevant.
• Report all medicines: include prescription medicines, over-the-counter items, vitamins, and herbal products.

Examples of categories to mention to your pharmacist or doctor

• Medicines that may affect kidney function (for example, certain anti-inflammatory medicines used long-term, some antibiotics, or other renally cleared drugs). Your clinician will judge the overall risk.
• Central nervous system medicines (such as sedatives or sleep medicines) if you also experience drowsiness or sleep changes.

Serious interaction warnings

Seek medical advice urgently if you experience severe allergic symptoms (such as swelling of the face/lips, breathing difficulty, or widespread rash) or if side effects become concerning.

Indications: who it is for

Campral is used for relapse prevention in people with alcohol dependence who are abstinent.

It is typically considered when:

• Alcohol use has stopped and abstinence is being maintained.
• There is a structured recovery plan involving counselling and psychosocial support.
• The benefit of helping prevent relapse outweighs potential risks.

Not intended for:

• Acute alcohol withdrawal management.
• Situations where abstinence is not the immediate goal.

Dosing: typical adult regimen

Dosing should be individualised. The most commonly referenced regimen for adults is two doses several times per day, but exact strength and schedule can depend on the product presentation and your clinician’s advice.

General dosing principles:

• Take as directed—do not adjust dose without medical advice.
• Renal (kidney) impairment: dose adjustments and suitability depend on kidney function. Because acamprosate is cleared renally, people with reduced kidney function may require a lower dose or may not be suitable for use.
• Liver disease: acamprosate is not extensively metabolised by the liver; however, your clinician may still consider your overall health and medication list.

Common practical schedule (example only):

• Divided doses across the day to maintain steady levels.
• Even spacing can support adherence and tolerability.

Always check your prescription label or product instructions for the exact dosing schedule for your strength and situation.

Safety profile: side effects and what to watch for

Many people tolerate Campral well. However, like all medicines, it can cause side effects.

Common side effects

• Diarrhoea (one of the more common effects)
• Nausea
• Abdominal discomfort
• Headache
• Dizziness in some people
• Fatigue

Less common but important reactions

• Allergic reactions (rash, itching, swelling)
• Severe skin reactions (rare)
• Worsening mood or new psychological symptoms should be assessed promptly, especially in people with a history of mental health conditions

When to seek urgent help

Seek urgent medical attention if you develop:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing or wheezing
• Severe rash, blistering, or widespread skin peeling
• Severe persistent diarrhoea leading to dehydration symptoms (e.g., marked dizziness, very low urine output)

Kidney safety

Because acamprosate is eliminated through the kidneys, kidney impairment can increase exposure and risk of side effects. Your clinician may check kidney function (e.g., creatinine/eGFR) and adjust the regimen accordingly.

Practical use tips (make it easier to stick with treatment)

Relapse prevention is most effective when medication is combined with support. These practical tips can make Campral therapy more manageable.

• Use a routine: link doses to daily activities (breakfast, lunch, evening, bedtime) to avoid missed doses.
• Pill organiser: a weekly organiser helps reduce dosing errors.
• Manage diarrhoea early: if loose stools occur, speak with a pharmacist. They can advise on hydration and whether dose timing should be adjusted (do not stop suddenly unless advised).
• Hydration matters: drink adequate water, especially if diarrhoea occurs.
• Track triggers: cravings can be managed using coping strategies—avoid high-risk situations where possible.
• Combine with counselling: regular therapy or group support (e.g., alcohol treatment services) often improves outcomes.
• Plan for stress and sleep: withdrawal-related stress and sleep disruption can increase relapse risk. Seek support early for these issues.

Alternative options for relapse prevention (Australia)

There are other medicines and non-medicine approaches used in alcohol dependence. Options depend on your goals, health conditions, and prior treatment history.

Other medication options (examples)

• Naltrexone (for some people to reduce heavy drinking/relapse risk—depends on abstinence status and clinical assessment)
• Disulfiram (works differently by discouraging alcohol use—requires strict abstinence and careful coordination)
• Other supervised therapies: medication choice may differ depending on liver function, kidney function, and drinking patterns

Non-medicine supports

• Counselling (CBT-based strategies, motivational approaches)
• Support groups and structured peer support
• Occupational and social support to reduce relapse triggers
• Addressing co-occurring conditions such as anxiety or depression through appropriate treatment

Your healthcare team can help compare options, including the best fit for your abstinence goals and medical profile.

Campral in Australia: market and legal context

In Australia, availability and prescribing rules are regulated under the national medicines framework and the scheduling system for medicines. Access to medicines for alcohol dependence is typically managed through established clinical pathways, and may involve review by general practitioners, addiction medicine specialists, or other credentialed healthcare providers.

Why this matters:

• Medication selection is often based on medical history, kidney function, and safety monitoring needs.
• Follow-up can help with adherence, tolerability, and relapse risk planning.
• Pharmacist support can assist with side-effect management and checking medicine interactions.

Recent guidance (high-level): Clinical guidance in Australia generally emphasises combining medication with psychosocial support and monitoring for side effects, adherence, and overall risk factors. Recommendations may evolve, so it’s important to rely on current advice from reputable Australian health services and your clinician.

Delivery and availability (online pharmacy)

Campral availability can vary by brand stock and strengths. Many online pharmacies offer convenient ordering with options such as:

• Home delivery to eligible areas
• Delivery tracking where available
• Discrete packaging to help with privacy

Stock and ordering: If a specific pack size is temporarily out of stock, reputable pharmacies may provide estimated restock times or alternative pack options (availability can vary).

Delivery considerations:

• Allow for dispatch time (commonly 1–2 business days, depending on location and courier).
• Use a reliable delivery address and ensure someone can receive the package.

Safety counselling checklist (before starting)

Before taking Campral, it can be helpful to ensure your clinician or pharmacist has key information about:

• Your kidney function (or history of kidney disease)
• Any history of allergy to medicines
• Your current medicines and supplements
• Any mental health history and current symptoms
• Whether you are aiming for abstinence (and your current drinking status)
